A native macOS browser built with SwiftUI and WebKit, with an iPhone and iPad companion.

• Runs Chrome and Safari WebExtensions: add them from the Chrome Web Store with Add to Browser in the address bar, from a ZIP, CRX, or folder, or from Safari extensions in your apps (Settings ▸ Extensions).
• Tells sites that turn away unknown browsers that it's Chrome or Firefox (View ▸ Website Compatibility), and opens pages that need another engine in another browser (View ▸ Open Page In).
• Syncs each profile's bookmarks and open tabs through iCloud with your other Macs, iPhone, and iPad, and hands pages off to them.

• macOS 15.4 or later; iOS and iPadOS 18.4 or later
• Xcode 26 or later
• XcodeGen

The iPhone and iPad app is the BrowserMobile scheme. iCloud sync needs a build signed with BROWSER_ICLOUD=YES (see RELEASING.md); other builds work without it.
